I'm ordering some Muscovies this spring, but I'm also ordering some standard ducks and geese from Metzer Farms. I was wondering this. If my Muscovies and other ducks can't come on the same week, could they still be raised together? If my Metzer's order came one week late, could those ducks and geese go right in with my Muscovies? And then let's go the other way. If my Muscovies came 1 week later, could they jump in with them? If the breeds matter my Metzer's ducks are going to be Welsh Harlequin, Rouen, Runner, and Blue Swedish, all females. I'm guessing I'll probably get an extra, which would be a male. I was also getting a pair of some sort of Buff Geese. Either Buff, Tufted Buff, or Large Dewlap Buff (they're importing that this spring). My Muscovies are going to be in pairs and I'm getting 4 of them. I'm getting 6 standard ducks (2 WH, 1 Rouen, 1 F&W Runner, and 2 Blue Swedish) and 2 geese (Pair).
